Busy Signals after hangup
I've not seen an answer to this in any forum.
I make a call through Asterisk, with a VOIP phone, doesn't matter which.
The call gets made, I leave a voicemail, or complete the call in some
manner, and the other side hangs up. I hear a busy signal on the phone
on my end.
If I have an extension that looks like this, after the hangup() is
executed, my phone gives busy signals until I

help with hclust
Hello,
how can I get the similarity value (i.e., the inner cluster similarity) that was used to cut a hierarchical tree at a specific height?
I would appreciate your help!
Best regards,

plot.hclust: strange behaviour with "manufactured"
This worked for me with your example:

storage.mode(x.hc$merge) <- "integer"

plot.hclust: strange behaviour with "manufactured" hclust object
I've been trying to get plot.hclust to work with a hclust object I
created and have not had much success. It seems that there is some
"hidden" characteristic of a hclust object that I can't see. This is
most easily seen in the following example, where plot.hclust works on
one object, but when this object is "...

[PATCH]add usb-ver format check to avoid usb-list error and incorrect usb-ver saved into config file
Add usb-ver format check to "usb-hc-create".
In original file, "usb-hc-create" allows usb-ver parameter as "2/2.0/2.0aaa". In low level hc create, it only uses the integer part (that is "2"), so there is no problem. But 2/2.0/2.0aaa will be saved into VM config.

tdb/tdbutil.c:tdb_chainlock_with_timeout_internal
Hello. I run samba 3.0.21c on RHEL AS 4 EMT_64 U3 and I've experienced a
strange problem where smbd will go (and stay) in the D state. While
waiting for IO (possibly), these smbd processes do not respond to client
requests, thus samba appears to be down. I could not kill these
processes via kill -9 , so I rebooted which worked.
The only error I could see out of the ordinary would be

x/y coordinates of dendrogram branches
...eration niveau of each step should be displayed at the
branches of the dendrogram.
For this I need the x/y coordinates of the branch-agglomerations of the
dendrogram.
The y-values are known (the heights of the agglomeration), but how can I
get the x-values?
> mydata <- c(1,2,3,4,5)
> hc <- hclust(dist(mydata), method="average")
> hc$height # these are the y-coordinates
[1] 1.0 1.0 1.5 2.5
I experimented with the dendrogram object because it gives the midpoints:

Cambiando limites en hclust()
Buenas tardes a todos,
Estoy interesado en cambiar los límites del eje y en un dendograma
construído utilizando la función hclust(). A continuación un ejemplo:
hc <- hclust(dist(USArrests), "ave")
plot(hc)
Hasta aquí todo bien. Si quisiera cambiar los límites del eje "y" de c(0,
200)? Al usar
plot(hc, ylim = c(0, 200))
no observo efecto alguno.
Qué puedo hacer?
Muchas gracias a todos.

R ignoring quantile() in source()d file
Can anyone explain this behavior? Essentially, I've created a short file
to be read in via source() that gets some descriptive information on a
series of variables in a data frame. For each variable, I do three
things:
print('last.hc.actors')
quantile(last.hc.actors,probs=seq(0,1,0.1),na.rm=T)
stem(last.hc.actors)
where the variable name is (in this case) last.hc.actors. All that is
fine, except that R seems to quietly ignore all the quantile() steps. I
narrowed it down to bare minimum, trying with a file, test.R, that
